I have made a custom viewgroup which has five imageview.
When I invalidate this viewgroup, why do all the "draw" methods of these imageview never get called back?
Doesn't the invalidate method traverse the viewtree from viewrootiml?

Is screen on when you call invalidate? It only force redraw if views are visible.. – Keivan Esbati Apr 15 '17 at 10:13

I have cleaned up the formatting of your question as well as provided syntax highlighting and grammar correction. This makes your question more presentable. – David L Apr 17 '17 at 21:24
